PROCESS 0F ROLLING TIE-PLATE BARS.

Specification of Letters Patent.

Application filed may 22, 1908. Serial No. 434,336.

No. 434,335, which plate consists of a plate proper having upon its lower face one or more longitudinal flanges or ribs and upon the upper face thereof a series of rail engag ing studs which are in vertical. alinoment with mid positioned directly over the flanges or r1 s.

In the present drawing I have shown one way of carrying out my present process, by reference to which drawing it will be noticed that Figure 1, is a perspective view of finishing rolls chewing a tie plate bar passing through the same, one end of the bar being shown in the finished state and the other in the semi-finished state. Fig. 2, is an eleva' tion of the rolls shown in Fig. 1. Fig. 3, is a crosssection through the tongue 5 and depression 6 of the roll 2. Fig. 4-, is a cross section of the semtfinished ban. Fig. 5, is a cross section of the finished bar.

The blank or semi-finished bar shown at A in Fig. 1 and in section in Fig. 4, consists of a strip. of metal having longitudinal ribs 7 on its upper surface, thereby forming an intervening groove 7 therebetween. The lower face of the bar A also has flanges or ribs 3. The bar-A may be rolled into its'ribbcd form in any well known manner from a billet or other original shape.

After the bar has been formed with the ribs and flanges, I place it in the rolls which have a closed pass andare provided with means for displacing the metal of the ribs into the flanges, means being provided, how-' ever, so as to leave transverse alining lugs 8 at intervals. apart, alternating with plane surfaces B, the lugs being left over or in alinelnent with the flanges 3.

I effect the required rolling of the bar by the type of rollers shown inFigs. 1, 2 and 3 of the drawings, by reference to which it will be seen the lower roll 1 has grooves 3 to re- 3 of the plate. The roll 1 also has collar portions 4-4 on each side of the grooved part, the colic l ing of larger diameter than the grooved to leave a plate pass which. is closed. roll 2 has grooves to receiver-he collar; of the roll 1, asshown inFig. L".

The tongue 5 on the upper roll 2 has suitably spaced pockets 6 into which some of the metal. of the ribs 7 is admitted as the bar is passed through the closed pass between the rollsl and 2, to leave an undepressed part of the ribs 7 in the form of lugs 8.

in practice the ribs '7 on the preformed bar have slight sloping sides and rounded corners, seeFig. 4,,the ribs leaving grooves 7 between one another in the plate, as shown. in Fig. 4. In passing through the final linishing rolls the bar ischanged in shape from that shown in Fig. 4 to the final shape shown in Fig. 5, by the dis )lacement of the metal from the ribs 7 into t .e flanges 3 suiliciently to form the flanges 3 in the desired final shape.

The provision of the closed pass between the rolls, formed by the tongue 5 projecting between the collars 4--4, enables the rolling to be carried out Without a depression of the edge of the plate at the location of the studs, and also prevents the formation. of a line of projecting metal along the side of the bar, as

would be the. case were ordinary superimposed rollers used.

As the bar asses through the rolls th loweredges of the flanges 3 are properly formed and sharpened. The difference in the shape of these flanges before and after assing through the rolls being respectively indicated in Figs. 4 and 5, of the drawings.

From the fore oing description, taken in connection with the accompany ing drawings, it is thought the complete construction, 0 oration and advantages of my invention will be readily understood by those skilled in the art to which this invention appertains.

What I claim is:

1. The process of manhfacturing a tie plate blank which consists in first rolling a illct of metal into a continuous tie plate bar having longitudinal ribs on one surface and longitudinal flanges opposed thereto on the other surface, and then rolling the bar soas to dis lace a part of the metal of the ribs into the flanges.

- 2. The process of manufacturing a tie plate blank, which consists in rolling a l illet of metal into a continuous tie plate bar hav ing a plane under-surface provided with lonand then rolling said body gitudina'l flanges and a plane up er surface provided with longitudinal ribs, the ribs and flanges being located opposite each other and then passing said strip through rolls having a properly shaped closed pass to displace some of the metal of the ribs into the flanges i and leaving projecting lugs formed by undisplaced portions of the ribs.

3. The process of manufacturing a tie plate bar which consists in first rolling a suitable body of metal into a bar having longitudinalribs on one face thereof and oppositely positloned flanges on its other face will displace a portion of the metal of the IlbS into the flanges and so as to leave transl verse shoulders or iugs alternating with plane 1 i. The process of rolling tie plate bars surfaces on one surface of the her.

one face thereof a plura 'ty of longitudinal flanges and upon the op os'ite face thereof a corresponding number of ribs positioned. 0p-

Which consists in utilizin as her having upon semis posite said flanges and in )assing said bar through final finishing rolls havin closed pass adapted to the final nishing of said flanges and constructed to displace a part of theinetal of the ribs intothe flanges and leave lugs at intervals.

5. The process of rolling tie plate bars Which consists in first rollin a suitable body of metal into a bar having longitudinal ribs upon one face thereof and oppositely positioned flanges on its opposite face, then rolling a. portion of the metal of the ribs into the body of the plate and into the flanges to in such manner as cause the final shaping of said flanges and leaving portions of the metal of the ribs in the form of lugs substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.
